[RPG] Unearthed Arcana Ranger: Does the Beast Conclave add your Proficiency Bonus to the Pet Companion’s damage dice


My group's ranger picked up the Unearthed Arcana for the Ranger class but I have felt it to be weak and have since investigated the document.

Your animal companion has abilities and game statistics determined in
part by your level. Your companion uses your proficiency bonus rather
than its own. In addition to the areas where it normally uses its
proficiency bonus, an animal companion also adds its proficiency bonus
to its AC and to its damage rolls.

Our ranger picked a Wolf at level 3, and is currently level 6.

The Wolf's normal stats in the PHB say:

AC 13

Prof. Bonus +2

HP 11 (2d8+2)

Bite: Melee weapon attack, +4 to hit, 5ft reach, one target. Hit 7(2d4+2) piercing damage.

If the ranger is level 6 and has a +3 prof bonus, the new stats should look like this in my opinion.

AC 16 (+3)

HP 29 (5d8+2)

Bite: Melee weapon attack, +5 (changing the +2 to a +3 yields +5) to hit, 5ft reach, one target. Hit 10(2d4+5) piercing damage.

Does this look right?

Your companion uses your proficiency bonus rather than its own.

It is important to note that it says, without condition, that the companion uses the Ranger's proficiency bonus. This means that, from this point on, it's proficiency bonus is the Ranger's proficiency bonus. Think of it as erasing the value on the creature sheet, replacing it with the Ranger's value, and then recalculating everything from there.

Upon looking at the UA document again, this is further supported as such:

Keeping Track of Proficiency

When you gain your animal companion at 3rd level, its proficiency bonus matches yours at +2. As you gain levels and increase your proficiency bonus, remember that your companion’s proficiency bonus improves as well, and is applied to the following areas: Armor Class, skills, saving throws, attack bonus, and damage rolls.

While the wolf has a listed proficiency bonus of +2, nowhere is it stated that this bonus is already included in the damage of the wolf's attack. We may infer that this damage is from the wolf's DEX mod, as is supported by the fact that the base to hit is +4, which would be +2 from proficiency and +2 from DEX, matching expectations for standard application of proficiency bonuses. The wolf's damage should be increased by a flat 3 points, making the roll 2d4+5, the same as you have stated. Furthermore, applying +3 to the base 13 also matches your stated 16 AC, and replacing the +2 with proficiency with +3 also results in a +5 to hit when added to the DEX mod. It is not explicitly stated that the bite is a DEX-based attack, but this is the only value that makes sense from the creature stats. Your math looks right.

Bonus Answer: No, the damage dice of the wolf's bite attack do not scale. It is important to consider that the wolf companion is not intended to be as powerful as an extra PC, but is instead part of the power of the Ranger to whom it belongs. Applying proficiency bonus to a damage source is a benefit other classes do not have, and this comes from an attack that does not require the use of any of the Ranger's actions. Also, consider that this attack has the potential to knock a target prone, leaving it more vulnerable to melee attacks until it has the opportunity to stand. Such a tactical advantage is certainly not weak.
